System and method for analyzing wavefront aberrations

Abstract

A system and method for specifying a vision correction prescription for a patient's eye, wherein in one embodiment, the method includes obtaining a wavefront aberration measurement of the patient's eye, applying at least one value from the wavefront aberration measurement to a statistical model trained using a plurality of objectively measured aberration values and a plurality subjectively measured visual acuity values as training data; and predicting a vision correction prescription for the patient's eye based on the at least one value and the statistical model.

Problems solved by technology

The human eye, namely the cornea and lens, can exhibit a variety of optical aberrations that diminish the optical performance of the eye, resulting in blurred vision.

The correction of blurred vision by lenses has typically been limited to correction of low order aberrations only, such as defocus and astigmatism.

Traditionally, high order aberrations, e.g. those describable with Zernike polynomials of the third order or higher, could not be corrected using lenses.

In addition, due to lens manufacturing limitations and expenses, defocus and astigmatism are typically only corrected in discrete steps, with any correction being made to the nearest one quarter (¼) diopter.

Unfortunately, the resolution of one quarter (¼) diopter results in incomplete vision corrections and limits the performance of the patient's eye.
